ESP32: Cannot send files to device

Expected behavior

Expected files to be created on device

Actual behavior

Getting error such as:

file.open("init.lua", "w")
Lua error:  stdin:1: attempt to call field 'open' (a nil value)
stack traceback:
    stdin:1: in main chunk
    [C]: ?
    [C]: ?

Test code

file.open("init.lua", "w")

NodeMCU ESP32 build unspecified powered by Lua 5.1.4 [5.1-doublefp] on IDF v4.4.3-dirty

Hardware

ESP-WROOM-32

Details

I built the firmware using these instructions: https://nodemcu.readthedocs.io/en/dev-esp32/build/#linux-build-environment
- although I had to comment out the line gdbgui==0.13.2.0 in sdk/esp32-esp-idf/requirements.txt, else I got a compile error for gevent (which I assume is a transitive dependency).

When booting, it says
